[PATCH v2 3/3] arm64: dts: ti: k3-j722s: Add wakeup domain peripherals specific to J722S

[Richard Genoud (TI)]

Introduce the "k3-j722s-mcu.dtsi" file to contain wakeup domain peripherals
that are specific to J722S SoC and are not shared with AM62P.
Previously, those nodes were squatting the k3-j722s-main.dtsi file which
should contain only main domain peripherals.
